**Name of the Vulnerable Software and Affected Versions** Jupyter notebook versions prior to 6.4.9 **Description** The Jupyter notebook is a web-based notebook environment for interactive computing. Prior to version 6.4.9, unauthorized actors can access sensitive information from server logs. Anytime a 5xx error is triggered, the auth cookie and other header values are recorded in Jupyter server logs by default. Considering these logs do not require root access, an attacker can monitor these logs, steal sensitive auth/cookie information, and gain access to the Jupyter server. **Recommendations** Upgrade to notebook version 6.4.10 or later. As a temporary workaround, consider restricting access to the Jupyter server logs to minimize the risk of exploitation.

**Name of the Vulnerable Software and Affected Versions** Jupyter Server versions prior to 1.15.4 **Description** The Jupyter Server is vulnerable to unauthorized access of sensitive information from server logs. When a 5xx error occurs, the auth cookie and other header values are recorded in the logs by default. Since these logs do not require root access, an attacker can monitor them, steal sensitive auth/cookie information, and gain access to the Jupyter server. **Recommendations** Upgrade to Jupyter Server version 1.15.4 to resolve the issue. As a temporary workaround, consider restricting access to the server logs to minimize the risk of exploitation.
